A covert method of investigation using facebook.com. Good for discovering a wealth of information about people you don't actually know.

person 1: Did you go to the _________ party last night?
person 2: No, but I was routinely facebook stalking (insert name of person you have never actually spoken to but have frequently visited his/her facebook profile)'s photos and saw pictures from it. It looked fetch.

Facebook Stalking, like regular stalking, allows the stalker to secretly gather information about the person they are interested in; the stalkee if you will. Unlike regular stalking, Facebook Stalking is less likely to have an illegal component and is generally accepted by it's voyeuristic victims. The argument being, that if you didn't want others to know about your life, you wouldn't post it all over the internet.

Person A: I was facebook stalking Jennifer for two hours last night.
Person B: Oh really?
Person A: Yeah, Amber added photos from her birthday party and Jennifer was tagged in one of them. However two weeks ago Jennifer RSVPed 'attending' on the guest list for Jack's birthday party which was the same night as Amber's. Then she updated her status to: "Jennifer is going on a date tonight" but according to her relationship status, she's not single!

Creeping on someone's facebook profile. Usually someone that you never speak to, only hear about and see in the hallways. Facebook stalking usually requires having set rounds, or in other words certain profiles that you like to visit each day. You read everything on the new's feed avidly. If someone's status is dramatic, you quickly click over to their page to see if you can find the cause. Changed relationship statuses bring you joy. Somehow a quick trip onto facebook turns into a three hour stalk fest of people that you only distantly know.

When an individual (male or female) scours another individual's profile, frequently checks their status updates, or reads their wall posts to and from other people. This is usually done either because the individual wants to know as much as possible about the individual whose profile they are reading, or they're bored and haven't looked at that person's profile yet after they've gained them as a friend on facebook. Some people admit to it, other's deny they have been doing it, even when caught in the act.
